Description

The invention relates to a harvesting device, namely a merger or pick-up swather, according to the preamble of claim 1. Furthermore, the invention relates to a method for transferring the harvesting device between a working position and a transport position.

From the EP 2 979 529 B1 a harvesting device designed as a merger is known. Mergers are also known as pick-up rakes. According to this prior art, the harvesting device designed as a merger has a support frame and a chassis. Furthermore, the harvesting device designed as a merger has pick-up members designed as pick-ups for picking up the harvested crop, as well as transverse conveying devices designed as belt conveyors for cross-conveying the picked-up crop. The support frame has a longitudinal member and cross members, the receiving members and transverse conveyor devices being received on the cross members.

To those from the EP 2 979 529 B1 To transfer well-known, designed as a merger harvesting device between a working position and a transport position, the receiving members and cross conveyors can first be folded upwards out of their working position around a horizontal axis, and then the receiving members and cross conveyor devices that have been folded up can be folded forward about a vertical axis . After EP 2 979 529 B1 it is therefore imperative to first fold the receiving members and transverse conveying devices upwards about a horizontal axis extending in the transverse direction and then to the front about a vertical axis.

Proceeding from this, the present invention is based on the object of creating a novel harvesting device designed as a merger or pick-up swather. This object is achieved by a harvesting device according to claim 1.

According to the invention, a displaceable crossbeam, which is arranged on a first side of the longitudinal beam, accommodates the respective receiving member and the respective transverse conveyor device, is displaceable from a working position about an axis extending in the vertical direction relative to a further displaceable crossbeam into an intermediate position and from this intermediate position via the further displaceable cross member about an axis extending in the horizontal longitudinal direction relative to a stationary cross member engaging the longitudinal member into a transport position. Furthermore, a displaceable crossbeam, which is arranged on a second side of the longitudinal beam and accommodates the respective receiving member and the respective transverse conveying device, is displaceable out of a working position about a further axis extending in the vertical direction relative to a further displaceable crossbeam into an intermediate position and out of this intermediate position the further displaceable cross member can be displaced into a transport position about a further axis extending in the horizontal longitudinal direction relative to a further stationary cross member engaging the longitudinal member. In the harvesting device according to the invention, the receiving members and transverse conveying devices can be moved out of their working position first around the respective vertically extending axis backwards and then from this intermediate position upwards around the respective horizontally extending axis upwards. This can improve the stability of the harvesting device when transferring between the working position and the transport position.

According to an advantageous development, the displaceable cross member, which is arranged on the first side of the longitudinal member and accommodates the respective receiving member and the respective cross conveyor, is out of the working position about the axis extending in the vertical direction in a first direction by 90 ° ± 5 ° to the rear in the intermediate position can be moved. The displaceable transverse support, which is arranged on the second side of the longitudinal support and accommodates the respective receiving member and the respective transverse conveyor, is 90 ° ± 5 ° to the rear out of the working position about the axis extending in the vertical direction in a second direction opposite to the first direction the intermediate position can be moved.

The rearward displacement of the receiving members and the transverse conveying devices about the respective axis extending in the vertical direction into the respective intermediate position is particularly preferred for reasons of stability.

According to an advantageous further development, the displaceable crossbeam, which is arranged on the first side of the longitudinal beam and accommodates the respective receiving member and the respective transverse conveyor, is in a first position from the intermediate position over the respective further displaceable crossbeam about the axis extending in the horizontal longitudinal direction Can be moved 90 ° ± 5 ° upwards into the transport position. The displaceable crossbeam, which is arranged on the second side of the longitudinal beam and accommodates the respective receiving member and the respective transverse conveyor, is 90 ° out of the intermediate position over the respective further displaceable crossbeam around the axis extending in the horizontal longitudinal direction in a second direction opposite to the first direction Can be moved ± 5 ° upwards into the transport position.

The subsequent displacement of the receiving members and transverse conveying devices from the intermediate position into the transport position about the axis extending in the horizontal longitudinal direction is also preferred for reasons of stability.

According to an advantageous further development, the respective receiving member is supported on a ground with feeler wheels during the transfer between the working position and the intermediate position. In this way, the stability of the harvesting device can be further improved during the transfer of the same between the working position and the transport position.

The method for transferring the harvesting device between a working position and a transport position is defined in claim 5.

Third cross members 24 , 25th and fourth cross member 13 , 14th are common across from the second cross member 26th , 27 about vertical axes 31 , which extend in the vertical direction, displaceable. The third cross member 24 , 25th grab the second cross member 26th , 27 and the fourth cross member 13 , 14th grab the third crossmember 24 , 25th at.

The harvesting device 10 still has a chassis 16 with wheels 17th . The landing gear 16 is also known as the main landing gear. About the wheels 17th of the chassis 16 is based both in a working position and in a transport position Harvesting device trained as a merger 10 on a surface to be processed or driven on.

The harvesting device 10 still has reception organs 18th as well as cross conveyor systems 19th .

The receiving organs 18th are designed as so-called pickups and are used to pick up crops from the ground to be worked. To a first side of the side member 12 are a first receiving organ 18th and a first cross conveyor 19th on the respective fourth cross member 13 recorded. On a second side of the side member 12 are a second receiving organ 18th and a second cross conveyor 19th on the respective fourth cross member 14th recorded.

The receiving organs 18th have pick-up prongs 20th , which are driven to pick up the crop from the ground about a transverse axis. Each of the receiving organs 18th is supported in the working position of the harvesting device 10 via jockey wheels 21st on the substrate to be processed. The jockey wheels are in a transport position 21st lifted from the substrate to be processed.

As already stated, the harvesting device has 10 in addition to the receiving organs 18th via the cross conveyors 19th . The cross conveyor systems 19th are designed as belt conveyors, with the transverse conveyors 19th that about the receiving organs 18th The crop picked up by the ground to be processed can be transported in a transverse conveying direction extending transversely or vertically to the longitudinal direction.

To the first side of the side member 12 is a first cross conveyor 19th together with the respective receiving facility 18th on the respective fourth cross member 13 recorded. To the second side of the side member 12 is a second cross conveyor 19th together with the respective receiving facility 18th on the respective fourth cross member 14th recorded, both of these cross conveyors 19th are designed as a belt conveyor.

As can be seen from the drawings, the transverse conveyor devices are seen in the harvesting direction or pulling direction of the harvesting device 19th behind the receiving organs 18th arranged.

In the in the 1 to 3 shown working position of the harvesting device 10 are the two cross conveyor devices designed as belt conveyors 19th that are on different sides of the side member 12 are arranged, seen in the transverse direction while minimizing the distance between the transverse conveyors 19th and with the formation of a transfer area 22nd between the cross conveyors 19th pushed together or moved towards each other. With cross conveyors driven in the same direction 19th can the crop over the entire transverse extent of the harvesting device 10 be promoted to one side of the same. In this case, the crop is then laterally next to the harvesting device 10 stored in a side swath from the ground.

In contrast to this, it is also possible that each of the transverse conveyor devices designed as a belt conveyor 19th each in the transverse direction outwards from the side member 12 is shifted away, thereby canceling the transfer area 22nd between the cross conveyors 19th a gap between the cross conveyors 19th is formed (not shown). In this case, cross conveyor devices driven in opposite directions can then 19th In the area of this gap, the harvested crop is combined into a so-called central swath and laid on the ground. With this relocation of the cross conveyors 19th also become the receiving organs 18th relocated.

As already stated above, there are fourth cross members in the area of both 13 , 14th of the support frame 11 one cross conveyor each 19th and one receiving organ each 18th on the respective fourth cross member 13 , 14th added, with the above training or cancellation of the transfer area 22nd the fourth cross member 13 , 14th together with the cross conveyor devices received on the same 19th and receiving organs 18th via link kinematics 23 relative to the third cross member 24 , 25th of the support frame 11 are translationally displaceable in the transverse direction.

Any link kinematics 23 has handlebars 32 , 33 that are attached to the respective fourth cross member 13 , 14th and third cross members 24 , 25th articulated attack to the translational displaceability of the fourth cross member 13 , 14th to ensure in the transverse direction.

Alternatively, the translational displaceability of the fourth cross member 13 , 14th can be realized by telescopic supports.

The present invention now relates to such details of the harvesting device 10 , with the help of which the same easily and reliably between the in 1 to 3 working position shown in 12 to 14th shown transport position can be transferred, with this transfer of the harvesting device 10 of the working position of 1 to 3 in the transport position of 12 to 14th the harvesting device occupies an intermediate position, namely the intermediate position of 7th to 9 , to then finally the transport position of the 12 to 14th to take.

To now the harvesting device according to the invention 10 from the in the 1 to 3 working position shown in 12 to 14th The transport position shown is to be transferred to the first side of the side member 12 arranged, the respective receiving organ 18th and the respective cross conveyor 19th receiving, displaceable fourth cross member 13 together with the respective third cross member 24 from the working position about the axis extending in the vertical direction 31 relative to the respective second cross member 26th and thus also relative to the respective first cross member 28 can be moved into an intermediate position. The respective third and fourth cross members are for this purpose 13 , 24 together with the respective receiving organ 18th and the respective cross conveyor 19th around the respective axis extending in the vertical direction 31 displaceable to the rear in a first direction, in particular foldable, namely by an angle of 90 ° ± 5 °, preferably by an angle of 90 °.

This is analogous to the second side of the side member 12 arranged, the respective receiving organ 18th and the respective cross conveyor 19th receiving, displaceable fourth cross member 14th together with the respective third cross member 27 from the working position about a further axis extending in the vertical direction 31 relative to the respective second cross member 27 and thus the respective first cross member 29 displaceable into the intermediate position, namely in a second direction opposite to the first direction again backwards by an angle of 90 ° ± 5 °, preferably by an angle of 90 °.

The ones on both sides of the side member 12 arranged receiving organs 18th and cross conveyors 19th are preferably shifted backwards at the same time.

In difficult ground conditions, especially in sloping positions, the two sides can be moved to the intermediate position according to FIG 4-6 be relocated to prevent the harvester from tipping over.

The sequence of 4th to 6th and 7th to 8th it can be seen that, based on the working position of the 1 to 3 first that to one side of the side member 12 arranged receiving organ 18th together with the respective cross conveyor 19th around the respective vertical axis 31 is displaced to the rear, the respective receiving member being moved into the respective intermediate position during this displacement 18th via its feeler wheels 21st supported on the ground.

After the receiving organ positioned on this side 18th together with the respective cross conveyor 19th from the in 1 to 3 working position shown in 4th to 6th The intermediate position shown has been shifted, the following is the one on the other side of the side member 12 arranged receiving organ 18th together with the respective cross conveyor 19th around the respective vertical axis extending in the vertical direction 31 shifted backwards so that then according to 7th and 8th both receiving organs 18th together with the respective cross conveyor systems 19th are shifted into their respective intermediate position.

The receiving organs are from their respective intermediate positions 18th and the cross conveyors 19th going to the different sides of the side member 12 are arranged, around a respective axis extending in the horizontal longitudinal direction 30th displaceable, namely by the fact that the same over the respective second cross member 26th , 27 relative to the respective first cross member 28 , 29 that is firmly attached to the side member 12 attacks, are displaceable in the direction of the transport position, in each case upwards by 90 ° ± 5 °, preferably by 90 °.

9 to 10 show an intermediate position in which the receiving organs 18th and cross conveyors 19th have not yet been fully moved up into the transport position.

In 12 to 14th however, are the receiving organs 18th and cross conveyors 19th each completely shifted upwards into their transport position, this for the different sides of the side member 12 arranged receiving organs 18th and cross conveyors 19th takes place in opposite directions.

Shifting to different sides of the side member 12 arranged receiving organs 18th and cross conveyors 19th from the intermediate position into the transport position is preferably carried out simultaneously or overlapping in time. This sequence when transferring the harvesting device from the working position into the transport position is preferred in order to always sufficiently stabilize the same when moving the harvesting device into the transport position.
